The rate of domestic violence assaults in Orange is 1.7 times more, per head of population, than the rest of NSW.

In the past 12 months, 285 incidents of this crime were reported to police, which is an increase of 16.3 per cent on the 245 cases during the previous year, NSW Bureau of Crime Statistics and Research data reveals.

But, use of Domestic Violence Evidence in Chief (DVEC) cameras by Orange police is helping victims, police said.

Central West Police District Superintendent Chris Taylor said the introduction of the technology has been a huge benefit for victims.

"When we go to a call for a domestic violence offence, the police who go there will use a camera and, with the permission of the victim, take a statement from the victim," he said.

"They'll record damage that's around the place, if there's been malicious damage.

"The advantage of that is we're recording for the court the exact circumstances of the offences, including the reactions of the victim, their injuries, even just showing that they're crying.

"It's very powerful evidence in court."

Supt Taylor said the footage often shows victims who are distraught, traumatised and injured.

"It shows all the circumstances of that related incident," he said.

Orange domestic violence liaison officer Senior Constable Granton Smith said while the victim must still be present in court at the hearing, the video statement has made it easier for them.

"It really was, months after the fact, an exercise in memory for the victim," he said of the delay in getting to court and prior to the use of DVEC.

"In terms of preparing people for court it's so much easier knowing they've got the video."

On the spike in domestic violence reports in Orange, Supt Taylor this increase was a win for police "because it shows that people feel secure enough that they will report incidents of domestic violence".

He said the Central West Police District was one of the leading districts in the region for our use of the DVEC cameras and that the footage helped towards convictions.
